10 They hate him that rebuketh in the gate, and they abhor him that speaketh uprightly.
[AD 220] Tertullian on Amos 5:10
They take the two sons as types of two peoples, the elder Jewish, the younger Christian.… But if I show that the Jew does not fit the type represented by the elder son, it will be admitted, in consequence, that the Christian is not typified by the younger. Admittedly, the Jew is called a “son” and an “elder son” since he is first by adoption, and although he resents the Christian’s reconciliation with God his Father (this is a point which our opponents seize upon most eagerly), yet the statement “Behold, how many years I serve you and I have never transgressed your commandment” cannot be one which the Jew makes to the Father. For when was Judah not a transgressor of the law? “Hearing with the ear and not hearing, holding in hate him who reproves at the gates and scorning holy speech.”

[AD 420] Jerome on Amos 5:10
(Verse 10) They hated the one who reproves at the gate, and they abhor the one who speaks truthfully. LXX: They hated the one who reproves at the gates, and they abhorred the holy word. These are the ones whom God derides with devastation and brings upon them destruction. They hate the one who reproves at the gate, that is, in judgment: either me, or other prophets who were sent to them, speaking truthfully or the flawless word, as Symmachus interpreted, or the holy speech, as Theodotion and the LXX translated. But at the gate, according to the ancient Jewish custom, there were judgments of the people, as we often read and frequently interpret, so that neither a farmer coming to court would be terrified by the crowded city and the new appearance, nor a dweller of the city would hurry far from the city and seek transportation for his livestock. This we have said according to the literal meaning. However, it is a great sin to hate someone who corrects, especially if they correct out of love and not out of hatred, if it is done in private to private, if with the inclusion of another brother, if afterwards in the presence of the Church, so that it may not seem like the accusation is made to detract from you but to bring forth the accusation for your improvement (Matthew 18). We often read in the Scriptures about the two gates, of death and of life, of vices and virtues, as in the Psalms: 'You have lifted me up from the gates of death, that I may declare all your praises in the gates of the daughter of Zion' (Isaiah 9:16). There is no doubt that it signifies the Church, the lofty mountain of Zion, and the city of the living God, heavenly Jerusalem, and the multitude of angels, and the early Church, who are enrolled in heaven. He who has been exalted in the gates of Zion will not be able to fear the gates of death, of which the Lord spoke to Peter: Upon this rock I will build my Church, and the gates of hell shall not prevail against it (Matt. XVI, 18). Clearly in another psalm we learn about the gates of virtue: Open to me the gates of righteousness: I will go into them and give thanks unto the Lord. This is the gate of the Lord; the righteous shall enter into it (Ps. XVII, 19). And finally, Wisdom, confident in the gates of the city, said: As long as the innocent possess justice, they shall not be confounded (Sap. VI, 11). I consider the gates of the city, that is, the souls of believers in Christ, to be virtues, through which Christ enters into believers. And because it is not written in which gates they hate the one who rebukes, whether in the wicked or in the good, we refer to both. The prophet accuses sinners standing at the gates of vices, and for this reason he is held in detestation by them. Or certainly the prophet himself stands at the gates and beginnings of virtues, and he is hated by those whom he rebukes, and it is not enough for sinners to hate the one who rebukes at the gates, unless they also abhor the holy word that is spoken from his mouth. For whoever does not receive the prophet does not receive the one who sent him (Matt. X). But if the holy word, or he who spoke perfectly, they abominated (moreover, the holy word is the Lord Jesus, of whom it is said: You will not allow your holy one to see corruption (Ps. XV, 10)), all the Jews saying anathema to Jesus, they abhor the word of God, which is both perfect and holy and immaculate. For the abomination of the sinner is piety. Whatever we have said about the Jews can be applied equally to the Gentiles and to heretics, all of whom abhor the holy Scriptures, in which the word of God is found. Some of them, while perversely interpreting what they read, place abomination in the House of God.
